There are two forms of human earwax: wet and dry. W is a dominant allele that produces wet earwax. In a sample of Spaniards, you measure the following genotypes: WW= 840, Ww =120, and ww = 40. What is the frequency of the homozygous recessive genotype? Select the right answer and show your work on your scratch paper for credit.

Crossing true-breeding pea plants with yellow peas with true-breeding plants with green peas yielded an F1 generation with 100% offspring plants with yellow peas. The F1 plants are self-fertilized and produce F2. In a randomly selected set of 100 peas from F2 you notice the following phenotypic numbers: 84 yellow and 16 green.  What is the observed frequency of the recessive allele in this F2 population?
